To all whom it may concern:

New Orleans,in theparish of Orleans and State of Louisiana, have lIlYGIltQCl certain new and useful improvements in Liquid- Fuel Burners, of which the following isa specification. V i I TlllS invention relates to liquid iuelburners and more particularl to fuel burners the oil and steam emergefrom said" tip or head by way of separate Openings or slots arranged in proximity to each other and preferably one above the other. 1

The objects of the invention are:

First, to construct and arrangethe parts of the burner so that the same may be manufactured with the minimum of cost and number of different parts, easily-and quickly assembled or. taken apart for inspection and cleaning. a

acter described in which the parts subject to wear and renewal can be made at a minimum of cost and easily and quickly replaced without the use of any special tool and skilled a i i i Third, to provide a burner in which the shape of the flame to suit the width or type of fire box or boiler, or control the amount of oil and steam hence the horse-power capacity of the burner for any particular width or shape of flame can be effected,'by simply and quickly substitutmg different shapes andthickness of combined spreader and Wear plates and without in any way altering the construction and arrangements of the main sections, castings or torgings forming the burner tip.

F ourth,.to construct a is only necessary to'change two plates com prising a part of the burner tip orhead, should it be necessary to modify its capacity or shape of the flame.

Fifth, other objects and advantages vof the invention will appear from the detailed disclosure, mode of assembling and manner of applying the invention which will be apparent from the following desc-r1pt1on,

The invention consists of structural characteristics and relative arrangements of elements which will be hereinafter more fully Second, to construct a burner oit the charhumor in which it w I described; and particularly. pointed out in; Be 1t known that 1, ANDREW lvlLLooKnTr, i a citizen of the United States, residmg at the appended claims. I a In the accompanying one sheet of-drawlngs, forming a part of this'specification and inwhich similar reference characters inditaken on line IIII of Figure 1; or atomizers in which an 011 plpe'and a steam pipe enter a burner tip or head and Figure 3 is a-front elevation of the burner tip or head; i i

,Figure 4 is a side view;

Figuree, is a plan view;

Figure'6 is a'rear elevation;

preferred form of the invention is 'illus 'trated, 10 and 11 represent apair of'hollow cOa'cting and.separable'sections, castings or forgings Which are preferably made identical in form and construction and are adapted to have their innerand flat-faces. orsides- Figure 7 is a plan'view of one oi the wear-' ividing 12, 12, opposed as shown. Internally screw threaded openings 13 :and 14 extend fronr and into rear end of the sections 10 and "11',

respectively, and adapted for the reception of pipes, not indicated, leading from any suitable supply of liquid fuel or oil and steam, as is common .in this class of and need'no' furtherrdisclosure.

Each of the sections 10 and 11 is provided with a recess, depression or chamber 15,

deviceswhich extends from either of the openings .4

13 or lLtO thefiat face or side'12 for puri sides 12,12, ofsaid sectionslO and 11 are 1 arranged a thin and imperforate central flat dividing plate 18, (see Fig; 9), having disposedon each side thereof aflat spreader plate 19' provided with a notch orfV-shaped incision 20 removed therefrom, ;as shown in.

Figure'S, and upon each exposed flat surface of each spreader plate 19 ,is superimposed a similarly shaped flat wearing plate 21 (see Figure 7) having preferably a circular perforation 22. Each of said plates 18, 19 and 21 is preferably provided with but not necessarily a pair of openings 23 without the zone or passage of the fuel, steam, or air passing through the burners and which register with each other and with the bolt openings 16, 16, in the sections 10 and 11, as shown in Figure .2; and when said siniilarly shaped plates are arranged .as just described, and the bolts 17, 17 passing through the sections 10 and 11 are tightened up, the plates 18, 19 and 21: are firmly and securely held in proper position between said sections 10 and 11 and with respect to each other in order to preserve the proper relation between the notch or V-shaped incision 20 of plate 19 and perforation or removed'portion 22 of plate 21 with respect to each other and the recesses or chambers 15.

When the sections 10 and 11 and plates 18, 19 and 21 are arranged as just described, it will be seen that there is formed a pair of separated and independent nozzle openings or slits 24 and 25, see Figures 1 and 3, in the forward end of theburner head or tip, and each of said slits is in communication with one of the recesses 0r chambers 15 and a liquid fuel or steam supply opening 13. or 14.

It will be manifest that a distinct advan tage is accomplished by the present construction, for the reason that the parts of the burner head, namely the dividing plate 18 and wearing plates 21,. which are intended to take the erosion due to the high velocity of the oil and steam passing through the burner and nozzle slots 24% and 25, may be quickly and easily replaced at a cost of a few cents.

It will also be seen that by substituting spreader plates 19, witha notch 20 having a smaller or larger angle. than that shown in Figure 8, the shape of the flame formed by the burner head or tip can be modified so as to be smaller or larger to suit the shape of the oil furnace or fire boX and efficiently apply the heat to the boiler. To vary the capacity or volume of fuel or steam supply for a given angle or notch 20 in the spreader plates 10, all that is necessary is tosubstitut-e spreader plates 19 of different thicknesses, which will accordingly form larger or smaller oil and steam nozzle outlets or slits 24c and. 25, without changing the shape of out, and while I have shown one and the preferred form of burner head, many modifications will readily suggest themselves to any one without departing from the scope of the invention as expressed in the claims.

Vhat I claim is 1. A fuel burner comprising two coacting sections, each section having its opposed side provided with a depression and a supply opening communicating with said depression, an imperforate dividing plate, and

a spreader plate. provided with a V-shaped. incision in its edge having the separated ends of the sides of the incision in the outer edge of the spreader plate and the meeting sides or pointed end of the incision in the inner section of the spreader plate and adjacent to and. on each side of said dividing plate and registering with a depression in one of said sections, said plates being so constructed separable sections with-the exposed sides of the spreader plates adjacent to and in contact with the separable sect-ions as to form two independent and separated slots at one end of said sections and having independent communication with one of said depressions.

2. A liquid. fuel [burner comprising two coacting and separable sections, each section havlng its opposed side provided with a recess and an entrance opening communicating with said recess, an imperforate dividing plate, a spreader plate provided with an ineision in its edge and adjacent to and on each side of said dividing plate, and a perforated wearing plate adjacent to the exposed side of each spreader plate, said plates, perforations and incisions being so constructed and arranged between said separable sections with the exposed sides of the and arranged between said wearing plate adjacent to and in contact with the separable sections as to form two jacent to the exposed side of each spreader plate, said plates, perforations and incisions being constructed and arranged between said separable sections with the exposed sides of the wearing platesadjacent, to and incontact with the separable sections, and formingtwo separated and independent slots'ibetween and at the end of the sections opposite to that of said entrance openings;

4,. A; liquid. fuel burner comprising, two

similar coacting and separable sections, each section having its opposed side provided with a recess, and an entrance opening communicating with said recess, an imperforate dividing plate, a spreader plate havin a V-shaped portion removed from its e ge and adjacent to and on each side of said dividing plate, and a wearing plate provided with a perforation adapted to communicate with one of the recesses in said separable sections and register with the V-shaped portion removed from the spreader plate, and adjacent to the exposed side of each spreader plate, said plates, perforations and recessed portions being so constructed and arranged between said separable sections with the exposed sides of the wearing plates adjacent to and in contact with the separable sections to form two separate and independent slots between and at the end of the sections. I

5. A liquid fuel burner comprising two similar coacting and separable sections, each section having its opposed side provided with a recess, and an entrance opening at one end and communicating with said recess, an imperforate dividing plate, a

spreader "plate having a V-shaped portion respreader plate and adjacent to the exposed side of each spreader plate, said plates, perforations and recessed portions being so constructed and arranged between said separable sections with the exposed sides of the wearing plates adjacent to and in contact with the separable sections so that the V- shaped portions removed from the spreader plates form two separated and independent slots at the end of the sections opposite to that provided with the entrance openings and each of said slots is in communication with one of said recesses through the perforation ture.
